Cárdenas 2012. Which one?

I've noted before how I am convinced Cuauhtémoc Cárdenas has never given up his dream that another Cárdenas will become president of Mexico, like his father Lázaro. While I was leaning toward the idea that he is above all promoting  his son Lázaro Cárdenas Batel, it seems the old caudillo and PRD founder has not given up his own ambitions at reaching Los Pinos, even at age 76: He recently noted to La Jornada that he is not promoting nor dismissing another run: "I'm neither blind or lame; I am healthy." The run-up to 2012 just got even more interesting.
